The Boston Acoustics SC85 5"x7" speaker features a tough copolymer woofer woofer that really delivers the beat. A butyl rubber surround keeps the cone under tight control for clear sound and reliable operation even at extreme playback levels. The 3/4" Kortec® dome tweeter sits in a contoured baffle that widens the dispersion of your high notes, providing clean, well-balanced instrumental detail throughout your car.

A built-in crossover makes sure the highs and lows combine smoothly, and protects the tweeter from sudden overloads. The compact neodymium magnet helps reduce the size of the SC Series speaker, so it can fit in more vehicles without any loss of fidelity.

Note: The oversized terminals on these speakers won't connect to a Crutchfield wiring harness. We recommend that you buy a 10-pack of female quick slides that you can splice onto our harness.

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Features

Tweeter: Each speaker uses a type-S2, 3/4" Kortec dome
tweeter. Kortec is a silky fabric saturated on the underside with a proprietary
stiffening agent. Because the inside surface of the dome is ultra stiff, the
tweeter tracks the signal with ease and produces an excellent transient attack.
Simultaneously, the soft, self-dampening top layer eliminates unwanted resonance,
so the sound is smooth and articulate. The Contoured Asymmetrical Tweeter Baffle
(CATB) delivers smooth extension and strong on-axis and off-axis response.

Woofer: The copolymer woofer cone has a durable butyl rubber
surround and stands up to the harsh automotive environment.

Crossover: All SC series speakers feature specifically tuned
crossovers to deliver the best blend between the tweeter and woofer. Each also
features tweeter protection for optimal performance and reliability.

Installation: The compact size of the magnet allows SC series
speakers to fit where other high quality speakers don't. Neodymium magnets offer
extraordinary power-to-weight ratio, approximately ten times the magnetic strength
of a conventional iron-ferrite magnet of equal size.

Speaker Terminals: These speakers have 0.25" positive (+)
terminals and 0.187" negative (-) terminals, which are too large for the
vehicle-specific speaker harnesses supplied by Crutchfield for many vehicle
applications. It is recommended that a pack of assorted female quick slides
(item #
263FQS10PK) be purchased and spliced to the harnesses to adapt them to the
speaker terminals.

I have long been a fan of Boston Acoustics car and home audio speakers. I had a set in my F150 that I loved although I can't remember the model number. So when I ordered these for my Shelby, I thought I was getting the same ones (they ended up not being the same as before). The sound quality of these is a lot better than the stockers in a mustang, but that isn't saying much. These speakers are decent sound quality but I was disappointed because they are not nearly as good as the other BA's I have owned. They are good if you are adding them to the stock radio as they do not require much power but if you're looking for a audiophile level speaker, this isn't the one for you. I paired these with Kickers Shelby 8" mid range speakers in the doors and the sound quality from the pair is average at best. I will be upgrading to a JL set of 5 ¼'s soon.

Great All-Around Speakers

After opening the speaker box, I did a quick test on the cone and it was extremely tight, which told me before I even installed them that there wouldn't be much bass muffle. And indeed, they're great. The bass is very tight on all types of music, great with a 7.1 EQ to tune each frequency band. Some songs vibrate my doors so much that I think I might need to do some reinforcement so the panel doesn't break apart. I will say they're more suited for dance/rap music or hard rock/heavy metal over indie/pop type stuff that doesn't hit very hard. The highs aren't the best I've ever heard, but I've got Alpine tweeters and crossovers to handle that. Still, these are amazing all around speakers, and are great if you have a factory deck with a 4 channel amp and 7.1 EQ like I do. I would recommend buying them now -- I was told Boston Acoustics is pulling out of the car audio industry, which stinks :(.
